showing a removable pin constituting a part of the means for transmitting motion from the actuating mechanism to the pump-valve or choker. Fig. 23 is an elevation of one end of the machine witha portion of the casing broken away to show the actuating mechanism. Fig. 24 is an elevation of one side of the machine with a portion of the casing broken away to show the actuating mechanism, and Fig. 25 is a side elevation of the machine on the side opposite the side shown in Fig. 24, a portion of the casing in this view also being broken away to show the actuating mechanism. Fig. 26 is a detail view showing a modification of the adjustable link 11, said modification consisting in equipping the link with a spring arranged to yield to excess pressure. Fig. 27 is a detail view of the upper end portion of the mold-cover-actw ating arm, showing the mold-cover pin in section; and Fig. 28 is a detail view of the mold-cover pin.

M machine comprises a main frame 1, a mol therein, a reciprocating mold-cover 2, and actuating mechanism. The actuating mechanism comprises a cam-shaft 3, arranged to actuate a lever or arm 4, which is pivotally connected to the mold-cover. For this purpose the mold-cover has a vertical opening 5 'therethrough, through which said actuatingarm projects. The projecting portion of 'said arm has a transverse opening 6, which opening is of circular form at its lower portion and has a tapering ofiset portion of less diameter extending upwardly. The moldcover pin 7 is a cylindrical bar of proper size to pass through the circular portion of the opening in the actuating-arm, and its middle portion is flattened so as to allow it to extend up into the reduced portion of said opening. Said mold-cover pin is thus locked in its place and its cylindrical ends project so as to overlap the upper surface of the moldcover and cooperate with grooves or bearin surfaces provided therefor on said moldcover. By this central arrangement of the actuating-arm its pressure is applied equally 'to the two sides of the mold-cover.

In the operation of casting it is necessary to apply considerable ressure to the moldcover, and it is desirab e to relieve this pres sure except during the operation of casting.

with a vertically-arranged hub 8, in which slides a rod 9, whose upper end carries agripping or clamping arm 10, arranged to project above the mold-cover. This gripping-arm is 'ournaled on the rod 9, so that it can swing orizontally to facilitate the assembling, repair, and adjustment of the parts; but during the operaton of the machine said grippingarm is fastened in roper position by a cotterpin or other suitalile fastening device. The lower end of said rod 9 is connected by an ad justable link 11 to a lever 12. Preferably said link 11 is made of sections connected by a turnbuckle 13, so as to be extensible. The lever 12 is pivotally mounted on the frame of the machine and bears upwardly against the periphery of a cam 14, mounted on a shaft 3 of the actuating mechanism. Fixed to the framework so as to pull upwardly on the free end of the lever is a spring 16 of sullicient strength to lift the rod 9 and the arm 10, carried thereby, clear of the mold-cover. By this arrangement the rod and the arm thereon are forced downwardly by the cam 14 on the driving mechanism and are raised auto-' matically by means of said spring 16, and the cam is so mounted with relation to the actuating mechanism as to apply-its pressure to said arm when the mold-cover is stationary and the type is being cast.

The means whereby the actuating mechanism is made to exert its pressure uponthe mold-cover comprises a spring arranged to yield to excess pressure. Preferably this spring 11 is inserted in the adjustable link 11 as an element thereof, as shown in Fig. 26.

The hub 8 of the device for gripping or clamping the mold-cover is at one side of said mold-cover, and in order to utilize the gripping-arm 10 for operating the type-ejecting plunger 17 said arm is made of angular form,

.so that its outer portion will be in aliuement with the mold-cover. The mold-cover is provided with an anvil 18 on its upper face, and the gripping or clamping arm has a bearing-plate 19, arranged directly above the point occupied by said anvil during the operation of casting. The outer end of said arm is provided with an adjustable screw 20, ar-

ranged directly above the point occupied by.

the ejecting-p unger 17 during the ejecting operation and constitutes the piece for actuating or transmitting motion to said plunger. This screw is adjustable vertically on said arm, an? it carries aE-s'haped piece or hook 21, who e upper portion is clamped between adjusting-nuts 22 on said screw and whose lower end is bifurcated to admit the typeejecting plungenbetween them. This typee ecting plunger 17 is mounted to slide vertically 1n the mold-cover and is provided with [shit a shoulder 23, beneath which the forks of the ed hook straddle said plunger, whereby sai hook will pull up said plunger incase it should get stuck. In the ordinary operation of the plunger, however, it is raised into its normal position by means of a fiat spring 24, mounted upon the mold-cover and engaging the collar on said plunger. The upward movement of said spring is limited by an adjusting-screw 25 provided for the purpose.

The mold is made removable bodily from the machine. The main part 26 of the mold comprises a block which constitutes the base and upon which all of the other stationary parts are secured. This base-block 26 is se cured by screws extending therethrough to a platform-27 mounted on the main frame of the machine. This platfo rm has a long downwardly-extending portion which includes the guide for the body-piece bar and upon which the various devices for adjusting the bodypiece are mounted. This platform 27 has its under side inclined and rests upon a wedgeblock 28, arranged to be moved endwise thereof by means of an adjusting-screw extending through an upturned flange on the projecting end of said wed e and working in a hole in the side of the mrild-platform. (See Fig. 23.) The vertical elevation of said )latform and consequently the elevation of the mold thereon are thus adjustable to aline accurately with the bearing for the mold-cover.

The middle portion of the base of the moldcover is raised to constitute the back cheek 31 of the mold and form the notched side of the type. Alongside of this back cheek and projecting forwardly thereof is the jet-plate 32, throu h which the jet-orifice 33 extends, said jet-p ate being secured to the base-plate by means of screws 34. The front cheek 35 of the mold consists of a block resting on the base and adjustable with reference to the back cheek. For this purpose the base-block 26 has a plate 36 fixed at its end and projecting upwardly in front of said front cheek. Through this projecting plate extends one or more headed screws 37, which cooperate with threaded holes in said front cheek, whereby said front cheek can be forced toward said plate. Also extending through said plate is one or more screws 3%, which bear at their ends against the surface of the front cheek, whereby said front cheek may be forced away from said plate. By this means the front cheek can be set to any desired adjustment, so as to vary the body thickness of the mold. j

The matrix 39 is at the end of the mold opposite the jet-orifice, as usual. Extending up through the base of the mold between the front and back cheeks is a vertically-reciprocating plunger 40, which is arranged to constitute the bottom of the 'mold' and to eject the type from the mold. This bottom piece is hereinafter designated as the body-piece, and the bar 41, upon which it is mounted, is hereinafter designated as the bod -piece bar. The several parts hereinbefbre described constitute the mold proper. The reciprocating mold-cover constitutes, in effect,

the top or the upper side of the mold; but as said mold-cover constitutes a permanent part of the machine it is not commonly considered as a part of the mold.

Thematrix 39 is mounted in a matrix-box 42, This matrix-box'is a piece of metal'having a slot or elongated socket formed in its face of proper cross-section for the matrixbox to fit. This socket or matrix-chamber has one end closed for the matrix to abut against it endwise. At the other end of the slot the matrix-box is equipped with a locking-lever 43, adapted to have one end bear against the end of the matrix, and thereby clamp it in position. To produce the proper pressure upon such lever, a screw 44 is mount ed on the matrix-box in position to bear against the tail of said lever, and in order to prevent excess pressure the tail of said lever is made resilient, as by slotting it lengthwise, as shown at 45 in Fig. 16.

The matrix ormatrix-box is mountedupon a matrix-carrier arm 46, so as to be free to adjust itself properly to the angle in which it rests. For this purpose the matrix or the matrix-box has holes 47 formed therein of a size sufficient to loosely receive supportingpins 48, provided therefor on the carrier-arm. The carrier-arm is mounted on a lever 49, provided with a spring 49*, arranged to cause said lever to exert an upward pressure on said supporting-pins, and a thrust bar 50 is mounted to turn universally upon a hand-lever 50*, against which bears a spring 50 so arranged as to push said thrust-bar inwardly against the matrix or its box. Both the carrier-arm and thethrust-bar are mounted-on a sliding frame 51, arranged to be pressed forward by the actuating mechanism during each operation of casting and to be withdrawn after such operation. By thus having the holes 47 in the matrix or matrix-box larger than the supporting-pins and having resilient pressure on said matrix or box the proper positioning thereof is secured before the sliding frame is pushed forward.

Opposite the front end of the matrix-box an upward extension of the base-plate of the mold is provided with a plate 52, which constitutes the lining-base. This lining-base 52 is arranged for the matrix or the matrix-box to abut against and is mounted on parallel pins 53, which extend through holes provided therefor in a piece fixed to the base-plate or front check, so as to constitute guides to secure the propermovementofsaid lining-gage. The movement of said lining-base is effected by means of an adjusting-screw 54, mounted in said fixed piece to bear against said liningbase. Instead of this device, thin distanceplates may be inserted vertically between said fixed piece and said lining-base, in which case a screw is used to draw said lining-base toward the fixed piece.

The width of the mold is varied bymeans of a micrometer arranged and operating as follows: The body-piece bar 41 is averticallymovable plate which is provided with the body-piece 40 of the mold and is arranged be tween the front and back cheeks of the mold, as hereinbefore stated. Near its upper end this body-piece bar is equipped with a pin 55,

extending laterally from the front side thereof. The under surface of this pin is squared off horizontally and rests upon a wearing or impact plate 56, which in turn rests against the upper horizontal face of the wedge end 57 of the micrometer bar or slide 58. This micrometer bar or slide 58 is prevented from turning,but is free to slidein a guide 59, which is arranged at a slight upward and inward inclination on a depending portion of the ver tically-adjustable mold-platform 27. Any suitable form of micrometer gage may be usedfor instance, that shown in Fig. 8. As shown in this figure, the projecting part of guide 59 of the micrometer-bar is made of cylindrical form. The exterior of this uide is screw-threaded and has a threaded s eeve 60 working thereon. One end of this sleeve has an internal flange 61 overhanging the end of said guide, and the other end of this sleeve is beveled off and marked with a scale. Said sleeve is slit lengthwise to make it resilient, and the exterior of said sleeve 60 is threaded and has a slightly-tapering threaded nut 61, working thereon to make the sleeve work properly on the thread of the guide. The end of the micrometer-bar or wedge-slide projects through the end of the micrometersleeve and is threaded and provided with a hand-nut 62 thereon. This nut 62 and the micrometer-bar 58 may be manipulated rapidly without affecting the adjustment of the gage, the operation beingv as follows: When the nut 62 is unscrewed, the micrometerbar may be pushed inwardly. nut is being screwed onto the micrometerbar, it does not afiect the position of the micrometer-bar until the nut bears against the flange 61 on the sleeve 60 but from the time when the nut 62 bears against the flange 61 its further screwing on draws the micrometer bar upwardly until the shoulder 63 on said bar bears against the flange 61 on the sleeve 60 and is stopped thereby. Between the end of the guide and the flange of the sleeve overlapping it the micrometer bar or nut has a collar or shoulder 63.

By manipulation, as above described, the micrometer bar or slide is moved endwise between the limiting positionsfixed by the end the impact-plate which in turn rests upon the When the micrometer-wedge) and the position of the body-piece thereby adjusted to secure the desired width or set of the type.

It is desirable to be able to lift the bodypiece bar while the machine is not in operation. For this purpose the machine is provided with a hand-lever 64, one end of which rests under the end of the body-piece bar, while its other end normally rests upon a bolt 65, provided therefor in the frame. In order to raise the body-piece bar, the hand-lever is pulled laterally off its rest and then pressed downwardly, whereby the opposite end of said hand-lever forces the body-piece bar upwardly against the force of a spring which normally holds said body-piece bar in its lowermost position.

For convenience of adjustment the front of the machine opposite the wedge end of the micrometer-bar and the impact-block is open to give free access to said im act-block. This impact-block is [-shaped. See Fig. 9.) Its top flange rests upon the wedge of the micrometer-bar and its lower flange is pushed downward by a spring 67, fixed to the frame or the depending portion of the mold-platform 27 to always keep the same in contact with the micrometer-bar. Preferably the s ring 67 is ahelical spring, which surrounds a ownwardly-depending stem 56 block 56. The end portion of this spring is screw-threaded and provided with a nut 67, which constitutes the lower abutment of the spring 67. As the upper end of the spring 67 bears against the fixed part the spring 67 normally holds the impact-block 56 against the wedge end 57 of the micrometer-bar. After the body-piece bar has been raised to its uppermost adjusted position the micrometer-bar and the impactblock thereon are lowered, and a die or distance-piece of the thickness desired for the set or thickness of the type to be formed is mounted upon the impact-block and between it and the pin of the body iece bar. Then the micrometer is manipu ated until said impact-block in its upward movement is forced against the overhanging pin of the body-piece bar, in which position the parts are accurately set for the desired set or thickness of the type. After the adjustment is thus effected the die or distance-piece is removed. The impact-block is locked in position by. means of a hand-,

screw 68, provided for the purpose. This handscrew 68 works in a threaded hole provided therefor in a piece-projecting from the guide of the body-piece bar 41. By turning the hand-screw 68 it jams or clamps the impact-block bodily against the stationary portion of the machine.

The vertical stroke of the body-piece bar is regulated so as to bring the top end of said body-plate in its uppermost position flush with the top of the mold. For this purpose an eccentric 69 is mounted (see Fig. 6) on the of the impact-" frame of the machine above a bolt or pin 70, arranged horizontally on the body-piece bar. This arrangement furnishes an accurate means for limiting the upward movement of the body-piece.

The proper position of the printing-face on the end of the ty e is determined by means of a horizontal pl ate or jstool 71, fixed upon the bas'eblook of the mold and vertically adjustable thereon b means of the usual intervening distance-p ates. Thisplate or stool 71 is secured" to the base block by means of set-screws 72", as illustrated in Fig. .12.

On the end of the mold co'ver is a grip ingjaw which consists of a plate or bloc 73, mounted to slide on two or more bolts or bars 74, which are screwed into the end of said mold-cover. Each of said bolts has a coiled spring 75 surrounding it, which springs hear at one end against the heads of the respective bolts and at the other against the grippingjaw 73 to-force it toward the end of the moldcover. The tension of said springs is regulated by turning the screw-bolts. The gripping-jaw is equipped with one or more .setscrews or bolts 76; arranged to cooperate with limitingstops or abutment-pieces 76", provided therefor on a fixed portion of the machine. These abutment-piecesare so located that they permit the gri ing-jaw to travel rearwardlywith the moid cover to a point close to the edge of the mold, at which point the movement of the jaw is stopped, while the rearwardmovement of the moldcover continues. In consequence of this arrangement the gripping-jaw opens above the mold-tha t is, the end of the mold-cover is separated from the gripping-jaw by a space directly above the mold-and wide enough to admit the type from the mold. The 'mold itself is of a common type, and the body-piece ejects the type upwardly into the grippingj aw in a manner well known in the art. The operation of casting is effected while the cover is in its foremost position, at which time said cover is clamped firmly down on the mold and just after the ejecting-plunger has ejected a type from the gripping-jaw.

As shown in Fig. 12, the lower portion of the inner face-of the clampin -j aw 73 is oflset, and said jaw is provided wit a fiatspring or resilient plate 77 countersunk flush with the face of the gripping-jaw and extending over said offset portion. In operation the spring portion of the jaw bears against the type and supports it by frictionpreparatory to the ejecting-plunger forcing the type into the perfecting mechanism or other receiving device therefor.

At one end of the lnold is the jet-orifice, which communicates with the melting-pot 78, as usual. This jet-orifice is an opening between the front and back jet-plates, and in the operation of casting type there is a jet formed 011 the end of said type. Heretofore ICO the casting portion, said dressing portion be-v ing arranged to slide relative to the casting portion. This jet-breaker 79 consists merely of a knife or sha edged. plate mounted upon the frame of t e type-dresser in such a osition that when the type-dressing portion is brought into operative position with relation to the type-casting ortion the type in the casting ortion will e forced against it andhave the jet removed therefrom. In

case the typle-making machine has no perfecting me anism separable therefrom the jet-breaker may be mounted on a slide provided especially therefor in an extension of the frame of the machine.

the main frame. The machine is provided with an ordinary melting-pot 78, together with an ordinary pumping mechanism, including the common pump-plunger 82 and pump-valves 117 and 119. This melting-pot is mounted upon a bracket 84, which is pivotally mounted on As. the ump mechanism is ordinarily mounted wit the melting-pot its connection to the driving mechanism is separable.

The jet-nozzle comprises a chamber 114, having an orifice'115, said chamber being connected to the pump-cylinder by a passageway 116. Within chamber 114 is a in or plug-valve 117, arranged to close an open the jet-orifice 115. This plugevalve is mounted on a .bar 118, which also carries a. 40

valve 119 to close and open the inlet to the chamber 114. There is an extension of bar 118, which is connected to a crank-arm 120, whereby said bar'and its valves may be reciprocated. The crank-arm is mounted on a rock-shaft 121, to which is aflixed a second crank-arm 122. This second crank-arm. is connected by a link 123, containing a turnbuckle 124 for varying its length, to a bar 125, arranged to slide vertically in theframe or bracket. The lower endof this bar is bent horizontally to form a bearin -face for the end of a pin 126, which fits hoosely in the bracket-frame. The lower end of the in rests u on the topside of a lever 127, lcrume in the main frame and carrying a roller 1,28, arranged to bear against a cam In order to keep the roller 128 in contact with its cam, a spring 129 is arranged to exert adownward pressure thereon. This spring surrounds a rod-130, which is vertically movable in the bracket-frame and bears at its upper end against said frame and at its lower end again st an adjustable shoulder 131 on said rod 130. The lower end of the rod bears against the lateral offset of bar 125,

whereby the pressure of the spring is transmitted through said rod and bar to the mov- -able pin 126, and thence directly to the camlever 127 In the construction shown in thedrawings the pum -plunger has an upward extension 85, whic extends upwardly through guides provided therefor on the melting-pot. A coilied spring 86 surrounds the upper end of 'sai again t the guide-support and at the other lunger-stem and bears at one end end a ainst a nut-87, screwed on the top end ofsai plunger, whereby said spring tends tohold said plunger in its uppermost position.

Pivotally'mounted on the meltinglpot is a engages horizontal lever 88, one'end of whic the stem of the plun er and the other end of which is connecte to a vertical rod .89. Around this vertical rod is coiled a spring 90, whose upper endbears against a shoulder on said rod and whose lower endbears against a stationary part ofthe bracket, whereby the spring tends to keep saidrod normally in its up ermost position. The lower end of said ro extends down through the bracket and has an enlarged head or collar 91.

Mounted on the main frame'of the machine is a vertically-movable bar 92, whose upper end extends laterally toward the pump mechanism and is bifurcated'in osition to straddle the vertical rod above t e enlarged head or collar, so as to interlock therewith. This last-mentioned bar is pivotally connected to one end of,a lever 93, which is fulcru'med in the main frame and which carries at'its other end a roller 94 in position to bear against a cam 95, mounted on the main cam-shaft of the machine or upon a shaft specially provided for the purpose. By this arrangement the coiled spring causes said roller to bear against the cam, whereby the cam is enabled to reciprocate the plunger of the pump.

It isdesirable to lock the plunger against accidental movement when the melting-pot is out of its working position. For this pur pose a pawl 96 is pivotally mounted on the pivoted supporting-bracket 84 of the melting-pot to swing horizontally with relation to said supporting-bracket. (See Figs. 4, 18, and 19.) The pawl is normally pressed against the vertical rod 89 above the enlarged head 91 thereof by means of a spring 97 provided for the purpose. Mounted upon the main frame is a fixed pin 98, arranged in such position that the'pawl bears against it when the bifurcated end of the link engages the enlargements of the vertical rod. By this arrangement the swinging of the melting-pot bracket causes the pawl to bear against the stationary pin, whereby the pawl is disengaged from the vertical rod simultaneously with the engagement of said vertical rod by the bifurcated link. When the'melting-pot bracket is swung away from the casting mechanism, the pawl engages and locks the vertical rod simultaneously with the disengagement of the bifurcated link therefrom.

For the purpose of adjusting the jet-noz-.

zle laterally or transversely to the line of motion of said mold-cover the outer or free end tion-clutch. In operation the turning of the.

hand-wheel will carry with it the ratchet and the shaft so long as the force required to move the bracket is less than the force required to lift the springs out of engagement with its ratchet. When the force required to further swing the bracket exceeds the force required to lift the stiff pawl, the hand-wheel turns idly, whereby it is impossible to distort the mold or to injure the j et-nozzle or nipple by jamming it too tight against the side bars of the mold.

The body-piece bar is actuated from the cam-shaft 3 by means. of a cam 104 thereon. This cam is arranged to bear against a friction-wheel 105, mounted on'the end of an arm 106, loosely mounted on a rock-shaft 107. This rock-shaft is mounted in bearings provided therefor on the depending portion of the mold-platform 27 and has fixed thereto a toe or a wiper 108, which is arranged to bear against the under side of a pin 109, fixed to the body-piece bar. Also -fixed to said shaft is a block 110, through which projects a set-screw 111 in position to bear against a rib on the loose arm. For convenience of construction the arm is preferably bifurcated and the block and its set-screw are mounted between theforks thereof. 'By manipulating the set-screw 111 the position of the friction-wheel on the end of said arm is varied with relation to the actuating-cam 104, and consequently the stroke of the body-piece bar is varied accordingly.

In operation the cam 104 strikes and trips the rocker-arm, and thereby raises and re-' leases the body-piece bar, which is returned to its lower position by means of a spring 113; but by reason of the arm 106 being loose upon its shaft the shock and jar on the bodypiece caused by such return is considerably relieved.

As shown at 112 in Figs. 10 and 11, the cheeks of the mold have connecting passageways extending therethrough to provide for the flowing of water to cool the mold.

Obviously the constructions hereinbefore described admit of considerable modification without departing from my invention, and I do not wish to be restricted to said constructions.
